摘要
New mixed variational analyses of a cylindrical embedded delamination in composite laminated plates are presented. The method of composite expansion, along with the Hellinger-Reissner variational formulation, is employed to derive new finite strip schemes for the interior and edge layer problems. Numerical results for a flat embedded delamination, part-through hole and a through-thickness hole are presented for symmetric and asymmetric plates under membrane or bending loading. Numerical results of the new two-dimensional mixed-hybrid finite strip scheme are presented to show the strip's behavior characteristics regarding spectral accuracy, finite element convergence and the satisfaction of equilibrium conditions.
